This study evaluates the role played by the legislature in one of Argentina
's most important economic reforms of recent decades: the reform of tax inc
entives for regional development. As implemented by the last military gover
nment, this system of tax incentives provoked sharp distributive conflicts
among provinces. Although a majority of legislators favored reform after th
e return to democracy in 1983, interprovincial conflicts erupted bargaining
problems that prevented the passage of reform legislation through regular
channels. Pro-reform legislators decided instead to delegate reform authori
ty to President Raul Alfonsin because he shared their interest in containin
g the fiscal cost of tax incentives. Subsequent uses of this delegated auth
ority by two presidents promoted the interests of the enacting coalition th
at supported delegation. These findings support the usefulness of delegatio
n models when carefully applied to Latin America and challenge theories tha
t neglect the different ways that legislators shape Economic reform.
